General Description
The APA2060 is a stereo fully differential audio power
amplifier with stereo Class-AB cap-free headphone driver
and LDO available in a TQFN5X5-32 pins package.
The built-in gain setting at power amplifier can minimize
the external component counts. For the flexible application,
the gain can be set to 4-steps, 6, 10, 15.6, and 21.6dB by
gain control pins (GAIN0 and GAIN1). The power amplifier’s
fully differential architecture provides high PSRR, in-
creased immunity to noise and RF rectification.
The APA2060 power amplifiers are capable of driving
2.4W at VDD=5V into 4Ω speaker, the cap-free headphone
drivers can provide 180mW at HVDD=3.3V into16Ω
headphones, and the LDO has a maximum 120mA
(4.75V) driver current for audio codec. The APA2060 pro-
vides thermal and over-current protections.
The cap-free headphone driver eliminates the DC block-
ing capacitors at outputs, save the PCB space. The inte-
gration of fully differential power amplifier, cap-free head-
phone driver, and LDO is the best solution for VISTATM
requirement and it can lower the total BOM costs.
